Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525184, here are decompositions:

7 + 31525177 = 31525184
157 + 31525027 = 31525184
193 + 31524991 = 31525184
421 + 31524763 = 31525184
463 + 31524721 = 31525184
541 + 31524643 = 31525184
577 + 31524607 = 31525184
643 + 31524541 = 31525184

Showing the first eight; more decompositions exist.
